In legacy Blynk I was able to send multiple values in array with something like:
Blynk.virtualWrite(V20, 111, 222, 333);
Then I was able to get array values via Blynk API ‘http://blynk-cloud.com:8080/tokenXXX/get/V20’. Result was an array as expected:
[111, 222, 333]
In Blynk 2.0, when I use same virtualWrite and call API ‘https://blynk.cloud/external/api/get?token=tokenXXX&v20’ to obtain array I got this:
I would like to know, where is a problem. Pin V20 in Datastream is Virtual Pin with type String (there is no Array option).
